My brother emailed me about what is the best deal for making your own t-shirts so I thought I might as well post it! The best deal I've seen is from Vistaprint, it's only $4.41 and that includes shipping. They have a ton of great designs to choose from. After you design your shirt you want to click on the shopping cart on the top right side on the page to go straight to checkout, that way you don't have to click "no, thanks" for other offers they will show you. When I've ordered in the past I always chosen the slow mail 21 day option but it's never close to that long.
